Marx and the Development of Critical Political Economy

Abstract

Although relevant analytical developments were provided over time by the critique of economic theory, they did not succeed in inhibiting the occurrence of a full-fledged revival of the neoclassical interpretation of capitalism. The development of critical economics and its capability of checking the influence of the dominant economic culture have been especially prejudiced by the failed integration between the analyses of Marx and Keynes. Following Keynes, once the ‘inducement to invest’ had been singled out as the central question for the explanation of output levels, one should have promptly acknowledged that on this very question Marx's analysis was significantly richer and more relevant than Keynes's—the richness and relevance of the former ultimately resting on the great attention Marx dedicated to the complex question of the influence of income distribution on the capitalists’ incentive to invest. It is argued in the article that through the study of this influence Marx succeeded in putting together the essential elements of a critical theory of effective demand, based on the principles and mechanisms that govern the distribution of income between profits and wages.
